Thanks for the reply, John. That makes sense, but I guess the route I took with that question was the wrong one. Basically, we're using this to connect to a Unix machine, and our people are running an application on it that requires them to 'release' one screen before they can get to the next. The way to 'release' the screen is with SHIFT+F16 (from a wyse dumb terminal). Obviously, there is no F16 key on the PC, but I've discovered that ALT+SHIFT+F6 is the PC equivelant. However, I can't pass that keypress through, it just puts the string up on the screen, doesn't actually 'release' it. Any thoughts on where I could find a solution? Thanks,
John
